By the way, Intel won't be introducing 32nm until late-2009 (according to their press info)
Why do you think it makes no sense? Have you developed electronic equipment? That was my business for some years, and I occasionally do some work even now.
High input impedance is a very important factor in protecting circuits.
In fact, some chips have impedances in the trillions of ohms. This keeps input current down, and also lowers the dangers of capacitance. With the very low voltages used in todays cpu's this is an important design element. high impedances isolate chips from the surrounding circuits.
I'm not saying that this is the only factor in chip life, but it does cause problems when things go wrong, or input voltages change with spiking, etc.
Below 32 nm, other factors become very important, including whiskering, which, though present as a problem for even 45 nm, has been solved at that size. At 32 nm it a worse problem, but has also been solved. At lower process sizes, it's still a problem, and solving it will be much more difficult.
By the way, whiskering is the main failure route for these thin lithium batteries we hear about that melt or burn.
32 nm will make an appearance in early 2009, or even late 2008, but you're right, I should have been more explicit. We will see the first sampling quantity of cpu's from 32 nm then, not actual shipping products.
